Relicanth

Longevity Pokémon ^#369

The reason it hasn’t changed at all in a hundred million years is that it’s apparently already a perfect life-form.

- Swift-Swim
  This Pokémon's Speed is doubled during rain. This bonus does not count as a stat modifier.
- Rock-Head
  This Pokémon does not receive recoil damage from its recoil moves. struggle's recoil is unaffected. This ability does not prevent crash damage from missing with jump kick or high jump kick.

- Sturdy
  When this Pokémon is at full HP, any hit that would knock it out will instead leave it with 1 HP. Regardless of its current HP, it is also immune to the one-hit KO moves: fissure, guillotine, horn drill, and sheer cold. If this Pokémon is holding a focus sash, this ability takes precedence and the item will not be consumed.
